The ten-headed and twenty-armed demon Ravana (Rawana) is the villain of the Ramayana, a great Hindu epic. Ravana’s power is a result of a boon given to him by the god Brahma. Ravana obtains the boon by meditating in devotion for ten thousand years while standing in the middle of five fires. After this, he proceeds to cut off each of his heads as an offering to Brahma. Just as Ravana is about to dismember his tenth and last head, Brahma appears to the demon and grants him any wish he desires. Ravana chooses to be made invulnerable to the powers of the gods and of other demons.
